SAFETY ATTACHMENT roe SHIPPING rnATronMs AND THE LIKE.

Application filed September 10, 1924. Serial No. "737,014.

declare the following is a specification} This invention relates to improvements in a safety attachment for shipping platforms and the like having for a particular object to provide a device of the character described which will positively prevent the closing of the shed doors without first elevating the platform, thus removing a constant danger to the freight men.

A further objectis to provide such a de vice in the form of a hook that will hold the plat-form in raised position or support it in lowered or operating position.

A further object is to provide such a device of simple construction, that may be readily applied and being capable of manufacture at a reasonable cost is thus rendered commercially desirable.

To the accomplishment of these and related objects, my invention resides in the construction, combination and arrangement of the various cooperating elements as shall be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the claims hereunto appended.

In the drawings, forming disclosure Fig. l is a fragmentary section of the warehouse, showing the platform lowered, the door open and the relative position of a freight car on the siding. V

Fig. 2 is a similar section of the warehouse, showing the platform elevated and the door closed.

Fig. 3 is a perspective of the platform retaining hook; and

Fig. at is a perspective of the simplified form of hook.

As many painful accidents have occurred a part of this by train men contacting with the warehouse platforms that were not elevated through carelessness on the part of the employees at the warehouse and as it is generally experienced that thoughtlessness is the chief cause of such accidents, often resulting in fatalities, I have designed this hook, to hold the platform in raised position or to rest on'the raised platform, that will positively prevent the closing of the door unless the platform is raised, thus necessitating the raising of said platform and-the removal of this constant danger before the watchman,

caretaker or other warehouse employee can I close the siding fronting doors.

1 Referring particularly to the drawings wherein like characters designate like parts throughout the several views, the numeral 0 indicates the warehouse in general, 6 in dic ates the door and 7 the platform, all of which are of conventional design, the door or doors G being hinged and the platform 7 also hingedly connected a short distance below the door or even with it.

Hinged to the am or jammed facing 8 is provided my safety attachment hook 9 being T-headed as indicated at 10 where it is connected by the pin or bolt 11 to the am facing 8. It is only when the body or stem of the hook 9 is in horizontal position and the arms of the T-hcad 1O consequently in vertical position when the door jam is cleared to allow the closing of the door 6. At all other times, as when the hook is supporting the platform, as-indicated in Fig. l, the T-head l0 interferes with the 3' am and restricts the closingof the door.

lVhen the platform is elevated, as illustrated in Fig. 2, and the hook 9 is resting on the top of the platform 7, the arms 10 are arranged vertically and no obstruction is offered the door which may be closed.

The form of hook illustrated in Figs. 1, 2 and 3 takes the form of my safety appliance and platform support combined, being of the extendible type, but in practice it may be found more practical to use the conventional chain or rod support for the platform and the simplified safety hook 12 as illus-f trated in Fig. 4: The sole function of this hook being to retain the platform in elevated position on which it rests and in vided which will fulfil all the necessary requirements of such a device, but as many changes could be made in the above description and many apparently widely different embodiments of my invention constructed v withinthe scope of the appended claims withoutdeperting from the spirit or scope thereof it IS intended that all matters contalned 111 the said accompanying specification'and drawings shall he interpreted-as illustrative and not in a limited sense.

What I claim as new and desire to secure by Letters Patent 1s:

1. A device of the character described remote end and provided with a door interfering T-head at-s aid connection, as and for the purpose specified.

EPA device ot the character described ep-tedto retain a shipping platform in e vated position comprising a bod to rest on he top of said platform with the depending end to embrace said platform pivoted to the warehouse, the remote end being provided with a T-head at said connection said T -head being adapted to interfere with the door when said hook is moved from horizontal position 5 4:. A satety attachment of the character described; comprising an extendihle hook lapted to support and retain a shipping attorn hingedl y connected the remote nd and provided with the door interfering Rhead at said connection, and for the purpose specified. I In testimony whereof I hereunto afl ixiny signature.
